20.500.12556/RUL-125587 Simply applicable method for microplastics determination in environmental samples Microplastics (MPs) have gained significant attention in the last two decades and have been widely researched in the marine environment. There are, however, less studies on their presence, routes of entry, and impacts on the biota in the soil environment. One of the main issues in the study of MPs is a lack of standardized methods for their identification in environmental samples. Currently the most commonly used techniques are thermal desorption gas chromatography–mass spectrometry (GC–MS) methods and pyrolysis followed by GC–MS. In this study, headspace-solid phase microextraction followed by GC–MS is proposed as a simple and widely applicable method for the de termination of commonly present polymer MPs (polyethylene terephthalate, polystyrene, polyvinyl chloride, polyethylene, and polypropylene) in environmental samples, for analytical laboratories with basic equipment worldwide. The proposed method is based on the identification of compounds, which are formed during the well-controlled melting process of specific coarse (1–5 mm) and fine fraction (1 mm–100 µm) MPs. The method was upgraded for the identification of individual polymer type in blends and in complex environmental matrices (soil and algae biomass). The successful application of the method in complex matrices makes it especially suitable for widescale use. polyethylene terephthalate polystyrene polyvinyl chloride polyethylene polypropylene gas chromatography mass spectrometry true false true Angleški jezik Ni določen Članek v reviji 2021-03-26 13:04:08 2021-03-26 13:04:08 2022-09-05 03:51:32 0000-00-00 00:00:00 2021 0 0 17 str. iss. 7, art. 1840 Vol. 26 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 543.51+543.544 1420-3049 10.3390/molecules26071840 57399043 18462981 RAZ_Sunta_Urska_2021.pdf RAZ_Sunta_Urska_2021.pdf 1 A1DF1EA19462D87FCEAFDBD3D91642F0 6df52a3c904a416c444d50afcd5a23277def587823dcc253a673b6b9375af9a1 7705bb82-9acd-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154211 https://www.mdpi.com/1420-3049/26/7/1840 0 6f9b8b84-9acd-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154210 Zdravstvena fakulteta 0 0 0
